What is


While constructing or renovating buildings and structures, the foundation needs to be strong enough to hold the structure steadily and evenly. Underpinning is the actual process of strengthening these foundations resulting in better stability and durability to these structures. In some cases the foundations of the structure might not be strong, stable and even experience slight movements which might result to cracks and visible damages to the structure.  To avoid further damage to the structure, a well planned and executed underpinning procedure helps to stabilize the foundations and reduction of cracks and physical damages.

In some cases, Underpinning might include series of procedures according to the nature of the damage or renovation. Procedures like excavations, steel works, pilings, injections, concreting, basements might be required in few cases as damages could be caused due to natural soil movement, earthquake, drought, flooding or other natural causes. Underpinning might also be required  in order to strengthen the foundation for addition of storeys in the existing building.
